any: Elastic Block Store (catch-all)

#
Service
ebs

Description

Catch-all entry for Elastic Block Store rules that match the service but not a specific eventName.

CompleteSnapshot

#
Service
ebs

Description

Seals and completes the snapshot after all of the required blocks of data have been written to it. Operation catalog is model-derived from the AWS SDK (botocore); this (eventSource, eventName) pair is confirmed by an observed CloudTrail record.

Example CloudTrail Event #

This is a projected export row, not a complete CloudTrail record: it shows only the envelope columns a SIEM export retained. The export never carried userIdentity, requestParameters, responseElements, sourceIPAddress, recipientAccountId, eventCategory, so their absence here says nothing about the real event. Account identifiers, ARNs and endpoint hostnames in eventID, requestID, resources, tlsDetails, userAgent are replaced with the placeholders AWS uses in its own documentation, so those values are structurally real but not the originals. errorMessage is withheld: it is free-form prose that names customer resources, which no substitution rule can find reliably. eventTime is withheld because the export renders it in the exporting system's local timezone rather than the UTC a CloudTrail record carries.

#
Service
ebs

Description

Returns information about the blocks that are different between two Amazon Elastic Block Store snapshots of the same volume/snapshot lineage. Model-derived from the AWS SDK operation catalog (botocore); the eventSource is inferred from the SDK endpoint prefix and no CloudTrail sample confirms it yet.

ListSnapshotBlocks

#
Service
ebs

Description

Returns information about the blocks in an Amazon Elastic Block Store snapshot. Model-derived from the AWS SDK operation catalog (botocore); the eventSource is inferred from the SDK endpoint prefix and no CloudTrail sample confirms it yet.

PutSnapshotBlock

#
Service
ebs

Description

Writes a block of data to a snapshot. Model-derived from the AWS SDK operation catalog (botocore); the eventSource is inferred from the SDK endpoint prefix and no CloudTrail sample confirms it yet.

StartSnapshot

#
Service
ebs

Description

Creates a new Amazon EBS snapshot. Operation catalog is model-derived from the AWS SDK (botocore); this (eventSource, eventName) pair is confirmed by an observed CloudTrail record.
